One end of the lever 646 is pinned to the lower end of the shaft 640 and one end of the lever-647 is engaged by the cam 618. A bracket 650 with the bearings 651 and 652 extends from the front face of the bellows frame 62. A pivot 653 is journaled in the bearing 652 and has fastened thereto the spur gear-654, which meshes with the teeth 239 of the disk 255. A pinion 655 is also fastened to the pivot 653. A pivot 656 is journaled in the bearing 651 and has fastened thereto the spur gear 657 which meshes with the pinion 655.

A link is represented with the members 670 and 671. A longitudinal slot 672 is formed in the member 670 and a pin 673 eX- tending from the member 671 engages the slot 672 for a lost motion connection. The upper end of the member 670 is pinned to the spur gear 657 and the lower end of the member 671 is pinned to the spur gear 612.

Referring to Figs. 5, 25, 26, an adjusting of the hubs 376, 426 and 476, re-

chart is represented to comprise a base 680, on which is represented a scale comprising the sectors 681 and 682. A pointer 683 with the guide leg `684 is pivoted to the base 680 by means of the pin 681. A rider 684a with cross lines 684b is movably supported on the leg 684. In the present instance twenty arcs designated by the numerals 1` to 2O are drawn upon the base 680. The arc 20 is divided into 20 main units and each of these units is again divided into smaller units. Arc 19 is divided into'19 main units. Arc 18 is divided into 18 main units and the remaining arcs are divided into a number of units` corresponding to the numerals at the end of the arcs. Lines are drawn from the axial center ofthe pivot 681 to intersect each of the divisions of the different arcs and the continuations of the latter lines are made to intersect the arcs,l the main intersections of which are indicated by the numerals in the upper arc of Fig. 25. The divisions on the arc of the sector 682 are determined as follows 1 the holder carrying the sensitive material is located at various equal distances from the `stationary frame 62 and reductions or enlargements are made as the case may be. The proportional reduction or enlargement is then directly measured from the photograph. The numbers appearing on the counters 685 and 686 being noted. Next the pointer 684 and the rider 684a are located on the points corresponding to the enlargement or reduction. These points are on the sector 681. The enlargement or reduction being determined by actual measurement of the test photographs. The numerals as noted on the dials 685 and 686 are then inserted at the proper points on the arc of the sector 682. To determine the intervening numbers on said arc the points just determined are located on cross section paper and the curve determined. The locations of the points with their numerals may then be readily determined either by measurement or by computation, using the well known equations of analytical geometry.

A numbering machine is secured to the cross girder 41 of the camera frame. It comprises the two housings 685, 686 that 'are connected by the spindle 687. A bevel gear 688 is fastened to the spindle 687. The counter with the housing 685 is used for enlarging and the counter with the housing 686 is used for reduction as will be explained.

A bracket 693 is fastened -to the' cross girder 41and has journaled therein the shaft 694 'on one end of which is fastened a bevel gear 695 which meshes with the vbevel gear 688-.

A spiral gear'696 is also fastened to the shaft 694. Journal brackets 697 and 698 are supported upon the cross girder 41 and have journaled therein the shaft 699. Spiral gears 700 and 701 are fastened to the opposite ends of the shaft 699. rlllhe spiral gear 700 meshes with the spiral gear 696. A spiral gear 702 is fastened tothe screw 48 and meshes with the spiral gear 701. vThe numbering machine is brought in action by means of the train of gearing between the screw 48 and the shaft 687.

The switch 33 already referred to comprises the two pair of long contact bars 710 and 711 which extend from the fiber supports 712 and 713 respectively. The supports 712, 713 have located below them the sheet of asbestos 714 which latter is carried on the 'wooden plank 715. Sheets 720 of asbestos cover the supports 712, 713 and sheets of ber 721 cover `the sheets of asbestos 720. v

Brackets 725 and 726 extend from the bellows frame 62 and have journaled therein the tubular shaft 727, on the upper end of which latter is secured the disk 730. A pin 731 extends fromv the disk 730. A connectingrod 732 h'as one end connected to pin 731 and the other end of the connecting rod is pinned to a leg 733 that extends from the plunger 457. To the lower end of the tubular shaft 727 is fastened a flange 734 of insulating material and from the latter extends the curved contact pieces 7 Wires 736, 737 extend from the electric motor 591, enter the tubular shaft 727 and are connected to the contact piece 735.

Wires 740, 741 extend from one of each of the pairs of contact bars 710 and 711 and connect with the electric lamp 743 which is used to illuminate the copyboard to be described. Only one lamp is shown but a number may be used. Mainline wires 745, 746 extend from a source of electric power and connect with one of each of the pairs of contact bars 710, 711 respectively.

On one 'of the cross girders 28 of the runway frame is mounted the port 750, held in place by the brackets as indicated at 751. Dovetailed guides 752, 753 are secured to the support 750. A copyboard 7 56 has extending therefrom the crossheads 757, 758 which respectively are supported inv the guides 752, 753. To the copy board 756 is secured the copy to be photographed. A pair ofgrooved guide bars 760, 761 are located parallel to the copyboard 7 56 and have their lower ends fastened to the side sills 26 and' 27 of the runway frame. The top ends of the guide barsv 760, 7 61 are connected to the support 750 by means of the cleats 762, 763. A pair of solenoids 768, 769 with cores 770, 771 are respective y supported on the guide bars 760, 7 61.

,A curtain roller 775 has extending therefrom journal pins 776, 777 which ported in the cleats 7 62, 763. An operating handle 778 extends from the pin 776. A

copyboard sup-l are sup-l Y the roller775. A bar 781 is supported at when the camera frame is moved in `the lower end of the curtain.

A bracket 785 is supported upon the front face of the bellows frame 62 and supports an electric push button 786. Wires 787, 788 for electric current' connected to a battery not shown are attached to the said button and connect with the said solenoids 768, 769. The push button 786 is in the path of a lug 790 extending from the sector 399.

To use the a paratus it will be first noted that the num machines having the housings 685, 686 are set with their counters at their zero positions when the lens of the camera photographs an object or picture its true and full size. Upon the camera frame being longitudinally moved in one direction, the counters on one of the numbering machines which I will designate as No. 1, will increase, while the counters on the other numbering machine remain stationary, and

the oppositevfdirection from the initial position, the counters on the second or- No. 2 numbering machine will increase, While the counters on No. 1 remain stationary. When a photograph is to be made which is either larger or smallerthan the copy on the copying board 756, the camera must be longitudinally moved from its initial or zero position, so that the photograph to be produced on the sensitized material in the plate holder 92 will be the proper size.

To locate the camera the proper distance from the copying board with the proper focus, the'operator uses the adjusting chart having vthe base 680, in case the picture is tobe made greater or smaller than the copy on the copying board. After he has determined the proportionate increase or decrease operator locates the rider of the guide leg 684, bver a number of one of the arcs indicated from one to 20, proportional to the size of the copy and in case of a reduction, the cross lines'of the rider 684* are then located over a lnumber which corresponds to the proportionate length required vfor said reduction, and in case of an enlargement the rider is located over one of said arcs corre-A sponding to the proportional size of Ienlargement, andthe cross lines of the rider are then brought over a number corresponding to the Size of the copy. In other words suppose a copy thirteen inches in width is to be photographedto produce a picture eleven i inches wide, the cross lines ofthe rider are brought Vover the number 11 on the arc marked'thirteen. The operator then reads the number on the sector 682 over which the pointer 683 is located. 'The camera is then longitudinally Vmoved from the copy board 756, .so that the counters of the numbering machine having the housing 686 agree Ywith the number on sector 682 under the.po1nter 683. Ifthe picture is to be an enlargement of the 'copy on the copyingboard, and if the` copy is eleven inches wide and it is to be enlarged to thirteen inches in width, the operator locates the rider on the arc No. thirteen and swings it until the rider is over number eleven on said arc. The operator reads the number indicated by the pointer 683 on the sector 682, and then moves the camera toward the copyboard, until the counters of the numbering machine having the housing 685 indicate the number on the sector.

By moving the camera frame Yhaving the side sills 38, 39, the rack 30 causes the spur gear 111 to rotate and with it rotation is given to the spur gear 113 through the bevel gear clutch members 112 and 115. The gear With said spiral toothed cone 160 causes the shaft 161 to rotate with a variable speed by reason of the longitudinal movement im.

partedto said bevel gear 164'. The shaft 161 through the spur gears 163, 169 and 167 transmits rotation to the shaft 165. The latter causes the bevel gear 168 to turn, and 'a variable speed of rotation is transmitted to the spiral toothed cone 17 6. lt will be noted that a uniformly variable speed is transmitted from the spiral toothed cone 160 to the spiral toothed cone 17 6. The shaft 17 5 rotates with theY cone 176 andthereby the .spiral gear 177 is turned. The spiral gear 177 turns the spiral gear 183, and thereby in size of the picture to be produced, thel the spiral gear 184 is turned at the same time. The gear 184 turns the spiral gear 189 and with the latter rotation lis given. to the spiral gear 190. The gear 190 rotates the spiral gear 191, by virtue of which the screw 48 is rotated.- With the rotations or" the screw 48 the nut 65 causes the bellows frame 160 to receive its requisite longitudinal movement. Byv means of the train of gears between the gear 111 and the screw 48 the bellows frame is moved in or out with a variable speed.

The mechanism just described obtains the proper distances between the lens and nsitized plate in the plate holder, for varying distances between the copy/board and the lens, thereby obtaining a correct focus for an enlargement or reduction of the copy and which results from the equality of the number on the sector 682 under the pointer 683 and the number indicated by the counter.

Should the proper focus not be obtained by these direct mechanical .connections by virtue of some latent imperfections, the operator retards the longitudinal movement of the bellows frame 60 by inserting the regulating plugs in the double racky 32. The bevel gear clutches 112, 116 are, then disengaged for an interval of timeA depending upon the lengths of the regulating plugs, and thereby the movement of the back of the camera or bellows frame 60 is retarded, and a proper focus is obtained.

The bevel gear 196 rotating with the screw 48 turns the bevel gear 333,l and thereby the shaft 332 is given rotation and with it the worm 334 turns. .The worm wheel 320 is turned by the rotations of the worm 334. Thegears 314, 315 and`316 are turned with the worm wheel 320. The gears 249, 272 and 292 receive rotation respectively from the gears 314, plungers 252, 276 and 296, are brought 1n proper position to coact with the stop 245, and thereby the disk 235 is enabled to move the diaphragm at proper times to obtainthe required exposures.

The diaphragm opening and the screen distance is of such size that the dots on the sensitized material will be of the proper shape and density. The gears operating the diaphragm are of such size that they will always keep the diaphragm opening of such size that the dots on the sensitized material will be of the proper density and size without shifting the screen.

The operator next partially turns the han-v dle 57 which moves the spur gear 605, and motion is transmitted to the spur gear 612. The spur gear 612 pulls down the link having the members 670, 671, which imparts movement to the spur gear 657. The gear 657 rotates the pinion 655 and thereby the gear 654 is rotated. The gear 654 meshing with the teeth 239 of the disk 235 partially rotates it in the direction of the arrow A to open the opening of the diaphragm having the blades 215 against the tension of the spring 302.

During the movement of the gear 612 the cam 613 lengages the rack 537 and raises the latter. The'movement of said rack causes the rotation of the gear 562 and the spiral gear 563. The latter turns the spiral gear 328-and thereby the pawls 322, 323 and 324 are swung. The said pawls 322, 323 and 324 respectively move the annular ratchets 260, 280 and 300 carrying respectively the cams 265, 285 and 303. The said cams respectively raise the plungers 252, 276 and 296 when the stop 245 is in its lowered position and the diaphragm is in its opened position. The spur gear 612 transmits motion to the spur gear 616. With the movements of the gear 616 movement is given to the cam 618 which latter engages the lever 647. The lever 646 is swung by the lever 647 and the fingers 641, 642 and 643 with the shaft 640 are raised.

315, and 316, Vand thev563 and 328. The

hubs 376,1 426 and 47 6l-force the bevel gears.

375, 425 and 475 to mesh respectively with the bevel gears 340,390 and 440. The said bevel gears are held -in mesh by the plungers 357, 407 and 457. The plunger 457 actuates the connecting, rod 732 and thereby the tubular shaft 727 is turned through ninety degrees, and closes the electric circuit between the main linewires 745, 746, the electric motor 591 and thelamp 743. With the movement of the spur gear 616 the bevel gear 617 through the bevel gear 629 imparts' a partial rotation to the shaft 625 and fingers 626, 627 and 628. The said fingers respectively actuate the disks 358, 408 sand 458 which cause the plungers 357, 407 and 457 .to lock with the grooves 377, 427 ,and 477 of the hubs 376, 426 and 476.

By means of the rotations of the armature shaft of the motor the worm 592 receives rotation, which in turn rotates the worm wheel 596. The worm 595l turns the worm wheel'602 and the latter causes the rotation of the spiral gear 603. The spiral gear 603 turns the spiral gear 532 and with it the shaft 517. Variable speeds are transmitted from the shaft 517 to the shaft 473 by means of the interposed gearing. The pairs of gears 482, 497-498, 432-499, 382 transmit speeds respectively to the shafts 423, 373. Figs.' 1 and 6 particularly show the positions of parts after the bevel gears 375 and 340 are disengaged. The bevel gear 375 rotates 'with with the bevel gear 340 rotates the disk 341, and by means of the bevel gear clutch members 344 and 350 the sector 349 receives rotation, so that it can mesh with its accompanying teeth 540 of the-rack 537 forcing it down. The rack 537 turns the spur gear'A to the pawls" 562 which transmits motion 322, 323, 324 by means of the spiral gears pawl 324 when turning engages the annular ratchet 300 and in conjunction with the cam 303 releases the plunger 296 from the stop 245. After the plunger 296 is released, the spring 302 pulls the toothed disk 235, until the stop 245 strikes the plunger 276. With the turning of-the disk 235 the teeth 237 thereof rotate the gea-r 226 and withit the pinion 225. The latter meshing with the teeth 211 of the disk208, causes a closing movement of the blades 215 of the diaphragm. The gears'between the motive power and gear 340 are preferably made of such size that the dial 339 and the sector 349 will make a complete revolution in one minute. In this way there can be obtained the changing opening, and any time from one second to one minute. The gears operating the dial 389 will make one revolution in 2 minutes and the gears operating the dial 439 are proportioned sothat the dial makes one revolution in four minutes.

posure in a half tone is strengthened. After The disk 341 continues turning until the plunger 357 engages the openin 343'thereof. he plunger 357 is thereby re eased from the groove 377 and the gears 340 and 375 are moved out of mesh and thereby the elements on the sleeve 338 and shaft 348 are stopped turning. To sector 349 with respect to t e rack 537 so as to engage it at the proper time, the operator pushes in and turns the knurled head 354 and locates the pointer 353 on they dial 339 so that the sector 349 will be properly positionerd with said rack.

The bevel gear 425 rotates with the shaft 423 and when in meshwith the bevel gear 390 rotates the disk 391 and by means of the bevel lgear clutch members 394 and 400, the sector 399 receives rotation so that it can mesh with its accompanying teeth 541 of the rack 537 forcing it down. The rack 537 turns the spur gear 562 which transmits motion to the pawls 322, 323 and 324 by means of the spiral gears 563 and 328. The pawl 323 when turning engages the annular ratchet 280 and in conjunction with the cam 285 releases the plunger 276 from the stop 245. After the plunger 276 is released, the spring 302 pulls theltoothed disk 235 until the stop 245 strikes the plunger 252. With the turning of the disk 235, the teeth 237 thereof rotates the gear 226, and with it the pinion 225. The latter meshing with the teeth 211 of the disk 208 causes a further closing movement of the blades 215 of the diaphragm. The lug 790 on the sector 399 after its engagement with the rack 537 engages the` electric button 786 to release the catches 770, 771 of the core of the solenoids 768, 769, to drop the curtain 780` of white material, by means of which the shadow eX- the curtain has been lowered in place in front of the copy on the copyboard the sector 399 continues turning with the disk 391, until the plunger 407 engages the opening 393 thereof. f The plunger 407 is thereby released from the groove 427 and the gears 390 and 425 are moved out of mesh, and thereby the elements on the sleeve 388 and shaft 398 are stopped turning. To properly locate the sector 389 with respect to the rack 537, so as to engage it at the proper time, the operator pushes in and turns the knurled head 404 and locates the pointer 403 on the dial 389, so that the sector-399 will be properly positioned with said rack. l

Thebevel gear 475 rotates with the shaft 473 and when in mesh with the bevel gear 440 rotates the disk 441 and by means of the bevel gear clutch members 444 and 450, the sector 449 receives rotation, so that it can mesh with its accompanying teeth 542 of the rack 537. The said rack turns the spur gear 562 which transmits motion to the pawls 322, 323 and 324 by means of the spiral gears pro erly locate the.

rotates the gear 226 and with it the 225. The latter .meshing with the teeth 211 l t 563 and 328. The pawl 322 when turning engages the annular ratchet 260 and in con- ]unctlon with the cam 265 releases the plunger 252 from the stop 245. After the plunger 252 is released, the sprin 302` pulls the toothed disk 235 until the having the blades 215 is closed. With the iaphragm turning of the disk 235 the teeth 237 thereof pinion of the disk 208 causes the closing of the diaphragm having the blades 215. The disk 441 continues turning until the plunger 1457 engages the opening 443 thereof. The plunger 457 is thereby released from the groove 477 and the gears 440 and 475 Pre moved out of mesh and thereby the elements on the sleeve 438 and the shaftr 448 are stopped turning. The sector 349 engages the rack teeth 540. The sector 399 is so angularly positioned relative to sector 349 that it engages the rack teeth 541 as soon as the sector 349 is disengaged from the rack teeth 540. To properly locate the sector 449 with respect to the rack 537 to as to engage it at the proper time, the operator pushes in and turns the knurled head 454 and loca-tes the pointer 453 on the dial 439 so that the sector 449 will be properly positioned with the said rack 537,

With the release of the said plunger 457 the arm 732. turns the tubular shaft 727 which disconnects the contact pieces 735 Y Erom the contact bars 710, 711, thereby opening the electric circuit between the motor 746 of `the source of electric current.

By turning the handleA 57 one half of a revolution, the rack 537 will be raised, so that the group of teeth 540 can engage the sector 349. Thereby all the elements between the spur gear 562 and the blades 215 are operated three times. By turning-the handle 57 one third of a revolution, the rack 537' 591, the light and the main line wires 745,

will be raised so that the group of teeth 541 lo plunger 296, and consequently the springv moves the disk 235 until the stop 245 engages the plunger 276.

By turning the handle 57 one sixth of a l revolution, the amount of rotation of handle 57 is determined by a decided stop being felt when the gears 340, 375, etc., mesh and in each instance the rack 537 will be raised, so that the group of teeth 542 will be positioned to be engaged by the sector 449, thereby the elements between the spur gear 562 andthe blades 215 are operated once. The reason `for the latter being that the spur gear 562 turns only one-third of a revolution. This results in not moving the annu-- lar ratchet 300 by means of the pawl 324 and the annular ratchet 280 not engaging, the

pawl 323. The annular ratchet 300 and 280.

not turning prevent the cams 303, 285 respectively from raising the plungers 296 and 276. Consequently the spring 302 moves th'e disk 235 until the stop 245 engages thev plunger 252. The handle 57 is returned to 'its normalposition after it has been turned. The coaction'of the motor 591, the pairs otl .gears 520, 485-521, 48%522, 483, the sectors 349, 399, 448 4with the rack 537, constitute a timing apparatus for the blades 215 of the diaphragm.

The diaphragm is opened by the handle '57' so that at least the stop 245 passes one of the plungers. `After the handle is released the spring 302 tends to close the diaphragm and the o enings depend upon the location of the p ungers 252, 27 6 and 296. The locations of the latter depend upon the location of the camera frame. The location of the camera frame depends upon the enlargement or reduction required. The amount of the turning of the handle 57 regulates the number of plungers that are to'be brought into action and this depends .not like the co y (all black) but lighter.

In a copy t at is very light, the screen 73 is moved a greater distance from the sensitized plate in the plate holder 92 and the light ra s are then diffracted ay larger amount. T e exposure is then decreased and a negative is produced which is not like the copy (very light) but which has a fair proportion of black and white.

By means of the chart with the base 180 the, operator determines the requisite reduction or enlargement desired and moves the camera frame having side sills 36 and 39, by means of the regulating handlev57, to a position s o that the numerals on the counters in the housing 683 agree with the number determined by the chart. By means of the appurtenances of the invention described the lamps 743 are lit. A further movement of the handle 57 drops the curtain 780 in operative position. The appurtenances of the diaphragm withblades 215 having been set, the blades 215 operate and a camera iframe movablyv supported thereon,
